All-around lighting includes general lighting and natural light. You want to ensure that at any time of day there is enough light for everyone to effectively use the space without incident and that any dark areas are minimized.
Don’t think that adding lights to your toe-kicks is a frivolous aesthetics-only decision. Strip lighting at the underside of base cabinets is a great way to create a night light that looks fabulous.
Adding lights as decorative elements helps set a mood in a space. Provided that general lighting is already installed using lights instead of wall art can be a decorative way to provide ambient lighting.
